The genetic variation in Korean evening primrose (Oenothera odorata L.) populations was examined to estimate the level of allozyme variation within populations using starch gel electrophoresis. 7 of 13 loci (Adh, Est-1, Est-2, Mdh-2, Pgd-2, Pgm-1, and Idh) revealed (Ps=43.2%) were polymorphic. The mean number of alleles per locus (A) and polymorphic locus (Ap) for populations were 1.64 and 2.46, respectively. The effective number of alleles (Aep) within populations relatively was low ranging from 1.08 to 1.22 with a mean of 1.14. Within populations, the mean number of allele per polymorphic loci (Ap) was 2.46, the mean number of alleles per locus (A) was 1.64, and the mean genetic diversity was 0.093. About 2.7% of the total allozyme diversity resided among populations (Mean G_ST=0.0274). F_ts, a measure of the deviation from random mating within 13 populations, was relative low (mean F_ts=-0.03636). The indirect estimate of gene flow, based on the mean G_ST, was high (Nm=8.88). Estimates of gene flow were consistent with low levels of genetic differentiation among populations.
